TL;DR: In this paper, the authors measured the OH concentration profiles outside a Pt catalyst at 1, 5, and 10 torr, and compared the measurements to a model describing a laminar stagnation point flow including a detailed mechanism with elementary reactions.

TL;DR: In this article, a discharge-flow system at 298 K was used to generate HS radicals for kinetic investigations, and the rate constant k(1) was obtained from the rate of H2S consumption under the condition [H2S] << [F]0======¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
Abstract: The reaction of H2S with atomic fluorine (1) has been studied in a discharge-flow system at 298 K to generate HS radicals for kinetic investigations. Mass spectrometric detection with single ion counting was employed. The rate constant k(1) was obtained from the rate of H2S consumption under the condition [H2S] << [F]0
It has been shown that the reaction (1) provides a clean source of HS radicals. From the disappearance of HS radicals upon addition of reactants and the formation of products rate constants for the following reactions have been determined:
The reaction of HS with O2 was also studied but it is too slow at room temperature to be followed with the present set up.

TL;DR: In this article, the authors consider the product-forming step as taking place in solid solution, and show that depending on the rigidities of the product molecule and of the parent crystal structure there may or may not occur, subsequently, crystallization of a product in its own structure.

TL;DR: In this paper, a review of recent developments in the study of reactive collisions with excited-state atoms, under single-collision conditions provided by crossed-beam and low-pressure gas cell experiments is presented.
Abstract: In the context of molecular reaction dynamics, the study of elementary reactions with excited species has developed rapidly in the last decades. This article reviews recent developments in the study of reactive collisions with excited-state atoms, under single-collision conditions provided by crossed-beam and low-pressure gas cell experiments. Application of high-resolution laser techniques allows selective electronic excitation of atomic reagents. This excitation is used to identify the key features of state-selected and spin-orbit effects, on both the reaction cross-sections and product state distributions. The polarized nature of the laser field is used to gain a detailed understanding of the reaction dynamics and stereodynamics, through the alignment of atomic orbitals. Several examples are discussed in the light of current theoretical models, a detailed analysis of the data leading to the identification of non-adiabatic processes taking place on excited potential-energy surfaces. New experimental developments will allow for an even deeper understanding of these elementary processes.
